Restoration

You're snapped out of your thoughts when you hear someone shouting, You realize you had been looking at your feet while you walk, you look up to see something - someone running toward your so-called 'group'. you freeze, holding both of your arms out to stop Axon and Aeryn from walking any further. Once they stop, you quickly reach into the bag you have slung over your shoulder and pull out a small handgun, pointing it at the approaching figure. The figure does not stop, only continues running. 'must not see it.' you think. With that, you raise the gun to the sky and pull the trigger. The firearms report echos through the arid desert air, causing your ears to ring. The figure continues to charge, only so much longer until it reaches you. 'deaf?...' you wonder, feeling a pang of guilt. Quickly shaking this off, you point the gun at the figure. But you don't get a chance to fire before Aeryn tackles you to the ground, sending the handgun flying out of your hand.
"Are you mad?! There's already less than a thousand of us left, we don't need to be killing anybody!" she scolds. Though, you're not focused on her and squirm your way out from under her, continuing to stare at the figure who is now only a few meters away. In the blink of an eye, the figure jumps at you, knocking you to the ground for the second time. Violently kicking at the creature's abdomen while gripping its throat, you manage to get it off of you. Now standing with the creature beneath your boot, you get a good look at it. It looks almost decayed. Sunken eye sockets, actually, the thing only has one eye, the other eye socket is completely empty. But that's the least unsettling thing about this undead being. Its nose is completely gone, and the flesh around its mouth looks... moldy... Or, what's left of it, anyway. Axon and Aeryn are blankly staring at the flailing creature, looks of confusion plastered on their faces.
"Well don't just stand there staring you buffoons! Give me the fucking gun!" you shout. Even though you know that is no way to talk to your superiors, you're in a bit of a panic.
Axon snaps out of his thoughts and reaches for the gun, tossing it to you. Quickly, you load it up and aim it at the thing's forehead.
"Say goodnight, disease-ridden scum." You mutter.
With no further words, you pull the trigger, sending a bullet through the creature's brain, it stops flailing nearly instantly and sends a splatter of blood and brain matter up into your face. You wipe your face off and spit into the sand, gah, you could taste it. Now, you put the gun back into your bag and announce,
"We need to get away from the area as soon as possible, if there's one, lord knows how many more could be lurking."
